PC Magagazine have reviewed the Samsung SGH-zx20 handset. 'Open up the zx20 and you'll find a small (1.8-inch diagonal), but quite bright 176-by-220 LCD screen, easily readable in sunlight, and a keypad of well-sized, raised plastic keys. Nicely designed, this phone felt great in the hand and when held against my ear. Voice quality on this quad-band world phone, whether through the earpiece or speakerphone, was absolutely excellent while using Cingular's 3G network in New York, and transmissions were clear as well. There's no noise cancellation, but voices punch through noise nicely. The zx20 also hooked up to my Plantronics Voyager 510 Bluetooth headset easily. You can even use your own MP3 files, stored on a MicroSD memory card, as ringtones.'
